Not sure exactly how this got to ChipGuide via eBay... but, I know it did while the auction was still going on because #48 is mine and I won it after the botched-up entry was submitted with both Images of one sine and not an obverse and reverse image and, it was like pulling teeth to try explaining how to correct the entry and that's why my name doesn't touch the entry while the others do... The proof is in the submission date and the date I won the auction and the proof that it's mine along with #38 are published in a Victor GADOIRY fixed pricepist in 1991, then the chips moved down the road from VG's office in Monaco to the person whom I bought them from in NICE, France... Dates and serial numbers can't be cooked.
